Last year, leaks about the Osama bin Laden raid disclosed the most sensitive operational details, imperiling future missions. This spring, a series of leaks resulted in reports of highly classified information about an intelligence penetration of al-Qaeda in the Arabian Peninsula, cyber operations against Iran’s nuclear program and details of drone strikes.

This summer, more leaks indicated that the president has signed a secret order authorizing support for Syrian rebels and revealed the supposed location of a U.S.-supported “secret command center.”

Ongoing FBI investigations have failed to deter further leaks. This is because White House staff is not currently subject to the same scrutiny that intelligence professionals are, such as polygraphs and monitoring of access to classified information. Also, the president can retroactively claim to have declassified information leaked by his staff.

Senator Dianne Feinstein, Chairwoman of the Senate Intelligence Committee, said the following,

“I think the White House has to understand that some of this is coming from their ranks,” she said at a World Affairs Council forum, according to AP. But on Obama, she said, “I don’t believe for a moment that he goes out and talks about it.”

Senator Feinstein walked some of this back but there is no question she was very upset about the leaks, many of which came from a book that quoted President Obama.

Presumptive Republican nominee, Mitt Romney said,

“What kind of White House would reveal classified material for political gain? I’ll tell you right now: Mine will not,” Romney said, as he denounced the leaking of intelligence secrets as “contemptible.”
